red raspberries

Raspberries are perennial plants. The canes, nearly thornless, grow from the crown one year, produce fruit the following year, then die. Some kinds produce a fall crop on the terminals of current season canes. Canes are stiff and may attain height of 10 or more feet in red and purple raspberries, and 4 or 5 feet in black. Commercially, they are usually supported by parallel wires along each side of the row, and headed to not over 6 feet high. Fruits, which are borne in loose clusters, consist of numerous seeds, each surrounded by fleshy pulp. These are attached to a receptacle until ripe, but when harvested the receptacle remains on the plant. Thus harvested fruit is hemispherical, either rounded or conic and open at the center. Red fruit is 0.5 to near 1 inch in diameter and similar in length; black fruit is somewhat smaller and flatter; purple fruit is as large or larger than red.


Season, bloom to harvest: 80 to 90 days.

Production in U.S.: About 25,000 tons commercial. Widely planted in home gardens.

Use: Fresh, canned, frozen, preserves, ice cream, jam.

Part of fruit consumed: All.
